Constructor & Destructor Documentation

◆ __construct()

ilADTBasedObject::__construct ( )

Constructor.

Tries to read record from DB, in accordance to current ILIAS behaviour

Returns: self

Definition at line 25 of file class.ilADTBasedObject.php.

        $this->properties = $this->initProperties();
        
        // :TODO: to keep constructor "open" we COULD use func_get_args()
        $this->parsePrimary(func_get_args());
        $this->read();
    }
